Persistent problems with trespassers: What can landowners do?
19th February 2020
Trespass can be a recurring nightmare for landowners. Walker Morris partners Karl Anders and Martin McKeague explain how recent case law can offer an effective option for landowners where earlier enforcement action has failed to secure permanent eviction.
What is the issue?
Many landowners have experienced the nuisance, damage to property and expense of dealing with trespassers. Whether it be travellers setting up encampments or protestors blockading sites or disrupting trading, trespass can cause direct, financial loss for landowners, reputational damage, and it can often have wider social impact for the general public or lawful occupiers who may get caught in the cross-fire.
Dealing quickly and effectively with trespassers can therefore be of vital importance. This is not always straightforward where the identity of any trespassers is unknown (so that they can’t be named in legal proceedings); and/or where, following an eviction, trespassers simply return or relocate to another of the landowner’s sites, very shortly afterwards.
What is the solution?
Fortunately for landowners, all indications from the flurry of recent case law in this area are that the courts will adopt a sensible and pragmatic approach and may be willing to order an injunction to remedy the situation.
An injunction has real “teeth” because it contains a penal notice. That means that if an affected person breaches the injunction, he or she is in contempt of court and can be imprisoned. Furthermore, in the case of local authority landowners, the Anti-Social Behaviour Police and Crime Act 2014 affords the court the ability to attach a direct power of arrest to the injunction, meaning that applying to the Court for a contempt of court order can be avoided before an offender is taken into custody.
The courts do not however grant injunctions without first undertaking a thorough assessment as to whether they are an appropriate remedy. Landowners and their advisers should therefore note all of the following legal and practical lessons to come out of recent trespass case law.
Key lessons from recent trespass case law
Boyd v Ineos Upstream Ltd  EWCA Civ 151
- There must be a sufficiently real and imminent risk of a wrong being committed to justify quia timet (that is, anticipatory/pre-emptive) injunctive relief.
- For an injunction to be granted against “persons unknown”, it must be impossible for the claimant to name the person[s] likely to commit the wrong; and it must be possible to give effective notice of the injunction.
- The terms of the injunction must correspond to the threatened wrong; they must not be so wide as to prohibit lawful conduct; and they must be clear and precise.
- The injunction should have clear geographical and temporal limits.
Norfolk County Council v Johnstone & Ors  1 WLUK 36
- Where other forms of enforcement action against trespass  have failed and the harm caused is not compensable in damages, an injunction can be awarded.
- The Boyd v Ineos principles apply on the granting of interim injunctions as well as final injunctions.
- So far as the temporal limit of an interim injunction is concerned, that will be a question of fact in each case. An injunction made for too long-a time could be subject to an application to vary. (In the Johnstone case, a three month interim injunction was ordered on the basis that it would give the claimant and the court the opportunity to assess whether injunctive relief was proving successful, and it would give both parties time to prepare for the final injunction hearing .)
Canada Goose UK Retail v Persons Unknown  EWHC 2459 (QB)
- Amid the pressure and the practicalities of injunction litigation, parties must not underestimate the importance of getting the legalities and the procedural aspects absolutely right .
Cuadrilla Bowland Ltd v Persons Unknown  All ER (D) 105
- So far as the Boyd v Ineos requirement for clarity and precision is concerned, this is particularly important where an injunction is targeted at persons unknown or at those who do not have legal representation.
- If there is any reasonable doubt as to whether a person’s conduct is covered by the injunction, the injunction may be unenforceable and may not be relied upon to establish a finding of contempt of court/imprisonment in the event of breach.
- An injunction term may fail the ‘clear and precise’ test if it is ambiguous, vague or drafted in such opaque, convoluted or technical language that it is not easily understood by its intended recipient.
- Context will also be key to determining the clarity and precision of an injunction term (“words which are clear enough in one factual situation may be unclear in another”).
Bromley v Persons Unknown  EWCA Civ 12
- This case is particularly relevant for local authority landowners dealing with the traveller community.
- The court, when dealing with a local authority’s application for an injunction against travellers, is primarily obliged to assess the proportionality  of the injunction in the terms sought.
- Local authorities should carefully consider the temporal and geographical range of any proposed injunction, and should ensure that alternative sites and other solutions have been explored.
- Local authorities should engage with the traveller community in a meaningful way, including (where appropriate) conducting welfare and equalities assessments.
- Whilst all cases have to be considered on their own merits, it would be wrong for a court to ignore the fact of a neighbouring authority’s successful injunction – if every local authority obtained an injunction, the travelling community would literally have nowhere to go. The cumulative effect of injunctions is therefore a relevant factor for the court to take into account as part of its proportionality assessment.

 The question of the temporal limit of the injunctions granted in Boyd v Ineos was not addressed in the Court of Appeal’s judgment; and it remains to be seen what temporal limit will ultimately be granted in the Johnstone case. Further guidance from the courts on temporal limits is likely to be ‘one to watch’.

 In the well-known case of Manchester City Council v Pinnock  2 AC 186 the Supreme Court ruled that a person at risk of dispossession of his or her home is entitled to challenge the proportionality of an eviction by a public authority under Article 8 of the European Convention on Human Rights
